The Nutrition Facts Label helps you understand the nutrients a food product contains. This fact sheet will help you read food labels, so that you can meet the needs of your kidney diet. Food labels have percent daily values listed for a set group of nutrients. These values are based on the Food and Drug Administration (FDA) recommended 2000 calorie diet. You may need more or less calories. Check with your kidney dietitian. Using percent daily values can help you choose foods that are within your special diet needs.
The Nutrition Facts Table lists the items that are required by law to be listed on food products. Food labels can help you see which foods are best choices for your diet.
In addition to nutrients, ingredients are also listed. All ingredients are listed in order by weight, with the item of the most weight listed first. If an ingredient is listed at the end, a very small amount was used in the product. Look at the list below of Ingredients to Avoid for help in reading the labels. Ask your dietitian to help you look at labels to best meet your needs.
The serving size listed tells what a single portion of a food is. The rest of the information on the label tells information about the serving size listed. If larger or smaller amounts of the food are taken, use the information on the label to figure out the nutrients for the portion you are going to eat. Be aware that the serving sizes listed may not be the same as the serving size on your diet plan. Talk with your kidney dietitian about how to use serving sizes to meet your needs. See "Putting it All Together," below, for portion sizes for CKD.
Calories tell you how much energy is found in a serving of the food. If you are trying to lose weight, you may be looking for foods with less calories per serving. If you need to gain weight, look for foods with more calories per serving. Ask your kidney dietitian what is best for you.
Fat and Cholesterol
Many people with CKD are on low fat and low cholesterol diets. Look at fat and cholesterol daily values to choose lower fat items, limit cholesterol and saturated fats. Look for foods with less than 10% daily value of saturated fat and less than 7% daily value of cholesterol. Choose lean or extra lean meats with just 7.5 - 15% daily value of total fat. If you need to gain weight, higher fat foods may be ok. Talk with your kidney dietitian about your needs.
Many people with kidney disease must limit their use of sodium. In general, look for foods that have no more than 6 to 10% of the daily value for sodium. Many low sodium products have added potassium. Look for potassium chloride in the ingredient list. If listed, be aware that the food will have a high potassium content. Caution should be taken if you are on a potassium-restricted diet. Food producers will begin to list potassium on the food label in 2018.
Carbohydrate, Sugars, and Fiber
If you have diabetes, this information is important for you. Choosing foods with less sugar and more fiber will help with your diabetes control. The total carbohydrate grams per serving will help you balance your meals. Every 15 grams of carbohydrate equals one bread/starch portion for diabetic and for kidney diets. A good source of fiber will have at least 10% of the daily value, while a high fiber food will have at least 20% daily value.
Protein is very important for keeping you healthy. Use the label, looking at the grams of protein listed. Each 7 grams listed equals one ounce of protein, or one meat serving on your diet plan. For example:
Ask your dietitian how much protein you need daily.
What about Potassium and Phosphorus?
Potassium and phosphorus may be listed as percent daily values, but it is not required. (Starting in 2018, manufacturers will be required to list potassium.) If potassium and phosphorus are not listed, it does not mean that they are not in that food. If percent daily values for potassium and phosphorus are listed, you can use them to help with your diet. Percentages for potassium and phosphorus are based on the Recommended Daily Allowances (RDA). The RDA is a guideline for the needs of healthy adults. Your needs are different when you have CKD.
|Percentages based on daily value for US food labeling - potassium 3500mg
|Percentages based on daily value for US food labeling - phosphorus of 1000mg
Ask your dietitian about your potassium and phosphorus needs. Some foods with higher levels may be on your plan if they are good sources of protein.
Pulling it All Together
Know the portion sizes for your diet plan:
||4 oz or ½ cup
||4 oz or ½ cup
|Pasta, rice, cereal
|Hotdog or hamburger bun
|Meats, protein foods
|Vegetables, fresh, raw
||1 small or ½ large
||4 oz or ½ cup
Know your diet needs for Calories, Fats, Cholesterol, Carbohydrate, Protein, Potassium and Phosphorus. Ask your kidney dietitian to help you. No single food will have all the nutrients at the levels you need. A balanced diet from a variety of foods will help you meet your needs.
In general look for items with:
||Percent Daily Value
|Potassium if listed
|Phosphorus if listed
Look at certain foods and choose:
|Meats: lean and extra lean
||Total fat 7.5 to 15%
||Sodium under 20%, Total fat under 15%
|Margarine and Vegetable oils
||Saturated fat under 10%
||Total fat under 15%, Sodium under 20%
||Sodium under 6%
Ingredients to Avoid
Banana, cheese, chocolate, cocoa, coconut, cream, dried fruit, melon, milk, molasses, nuts, orange, peanut butter, potassium chloride (KCl), potato, raisins, dark rye flour, frozen vegetables packed with sauce, spinach, tomato, wheat or oat bran.
